    June 10, 2012 Image of the Day: Evidence of a Past Universe? Circular Patterns in the Cosmic Microwave Background              Stephen Hawking has said: "We should look for evidence of a collision with another universe in our distant Past." Some experts believe that what we call the universe may only be one of many. Is there any conceivable way that we could ever detect and study other universes if they exist? Is it even falsifiable? This was a key question Hawking was was asked in an interview with the BBC. "Our best bet for a theory of everything...

    Latest research deflates the idea that the Universe cycles for eternity.Our view of the early Universe may be full of mysterious circles — and even triangles — but that doesn't mean we're seeing evidence of events that took place before the Big Bang. So says a trio of papers taking aim at a recent claim that concentric rings of uniform temperature within the cosmic microwave background — the radiation left over from the Big Bang — might, in fact, be the signatures of black holes colliding in a previous cosmic 'aeon' that existed before our Universe.

    Have we found the universe that existed before the Big Bang? The current cosmological consensus is that the universe began 13.7 billion years ago with the Big Bang. But a legendary physicist says he's found the first evidence of an eternal, cyclic cosmos. The Big Bang model holds that everything that now comprises the universe was once concentrated in a single point of near-infinite density. Before this singularity exploded and the universe began, there was absolutely nothing - indeed, it's not clear whether one can even use the term "before" in reference to a pre-Big-Bang cosmos, as time itself may...

However, physicist Roger Penrose of the University of Oxford, UK, and psychologist Stuart Hameroff of the University of Arizona in Tucson have proposed that consciousness might arise from wave-like quantum-mechanical effects involving protein...
